A Radio-Telemetry System for Navigation in Free-Roaming Rats
نویسندگان
چکیده
A multi-channel implantable electrical stimulator is described based on wireless microcontroller CC2430. PWM conversion circuits to DAC and the voltage-controlled current source are designed, the latter of which is needed for electrical stimulator circuits. Through the multi-channel analogy switches, positive and negative pulses on the rat brain areas can be achieved. The positive and negative waves are shown to verify the validity of the circuits.

Free roaming dogs: a threat to public health
Free roaming dogs are increasing in numbers. They live in unhygienic conditions and are not vaccinated mostly. They create several problems in the community, particularly health threats to human. Dog biting is a commonly reported case in some hospitals in Bangladesh. Rabies is one of the killers of people in Bangladesh and transmission occurs mostly due the dog biting. Death commonly occurs in ...
متن کاملReal-Time Telemetry System for Monitoring Motion of Ships Based on Inertial Sensors
A telemetry system for real-time monitoring of the motions, position, speed and course of a ship at sea is presented in this work. The system, conceived as a subsystem of a radar cross-section measurement unit, could also be used in other applications as ships dynamics characterization, on-board cranes, antenna stabilizers, etc. This system was designed to be stand-alone, reliable, easy to depl...
متن کاملHome Range, Habitat Use, and Activity Patterns of Free-Roaming Domestic Cats
We used radio-telemetry and collar-mounted activity sensors to compare home range size, habitat use, and activity patterns of owned and unowned free-roaming cats on the outskirts of ChampaignUrbana, Illinois, USA. Owned cats (3 M, 8 F) had smaller home ranges than unowned cats (6 M, 10 F), but we failed to detect consistent differences in home range size between the sexes or among seasons. Home...
متن کاملUsing GPS to enhance digital radio telemetry
The precise time available from the atomic clocks orbiting the earth in GPS satellites is used in many systems where time synchronization is important. The satellite clocks are monitored and adjusted by ground based control telemetry to within one microsecond of Universal Time. A number of commercial GPS receivers have the ability to provide a time synchronised output, typically one pulse per s...
متن کاملGPS Jamming Detection in UAV Navigation Using Visual Odometry and HOD Trajectory Descriptor
Auto-navigating of unmanned aerial vehicles (UAV) in the outdoor environment is performed by using the Global positioning system (GPS) receiver. The power of the GPS signal on the earth surface is very low. This can affect the performance of GPS receivers in the environments contaminated with the other source of radio frequency interference (RFI). GPS jamming and spoofing are the most serious a...
